High resolution spectroscopy can be obtained with Phoenix in the 1-5µm region, within the bandpasses of the blocking filters mounted in the instrument. A small range of narrow slit widths (providing different resolving powers) is available. The properties of the slits and blocking filters are described in this section, as well as information about exposure times and observing hints.

Observing Overheads

Current estimates are that the overheads associated with each new science target (for target acquisition, telescope, WFS and instrument re-configuration etc) depend upon the guide configuration chosen for the observation.

Setup times for various observation types are:
